Pass a URL in a GET for PHP -

I have to pass the URL using a GET address. To give an example I've tried:

  http://www.example.com/area/#http://www.example.com/area2/   
 I have also tried to replace the next slash with the other characters but it does not seem to work. How do you get the URL in GET?   
 
 
 As I understand, you should use.  
 The function lets you create a string that can be used as a link.  
 You should use it like this:  
  $ link = 'goto .php? Link = 'url_encode ($ _ post [' TARGET_SITE ']);   
 And when you were going to redirect to a user defined site (such as), you can decode the given parameter like this:  
  $ Decoded_link = url_decode ($ _GET ['click']); // It is now safe to use the given URL (for example, I can redirect there) header ('location:'. $ Decoded_link);   
 Hope it helps.
